Can you please explain each how to solve, step by step (except for 5&6 only answer needed). Thank you so much!!

Match each trigonometric function with one of the graphs. -- f (@ ) = tana -- v f (@ ) = sect -- v f (@ ) = oct -- v f (@) = cote H N WA UI X 1. -2x 3 1 3 x 2 x 2 1 2 -5 X 2. -2n 3 1 3 x 2 1 NA 2 2 -1 2 -55 UJ 2 X LW 2 n 3. -2n A W N H un 4 Now X 2 x 4 -21 -2 -3 4 5Using the sum and difference of cosines formula, find the exact value of cos 57T 12 Enclose numerators and denominators in parentheses. For example, (a - b)/ (1 + n) sin (a ) OO III ? COS 12 =If sin t = and t is in quadrant I, find the exact value of sin (2 t), cos (2t), and tan (2 t) algebraically without solving for t. Enclose numerators and denominators in parentheses. For example, (a - b)/ (1 + ). sin (a) ? sin (2 t ) = sin ( a) ? cos (2 t ) = sing a ? tan (2t) =Use the fundamental identities to fully simplify cos (-*) sin (-x) csc (-x). Enclose arguments of functions in parentheses. For example, sin (2x ). sin (a) cos (x) sin (-x ) cso (-x) =7. Simplify the trigonometric expression below by writing the simplified form in terms of cosa. Enclose arguments of functions in parentheses. For example, sin (2x ). sin (a) III ? tantcota = CSCE
